Observer Access and LTI Tools in Canvas LMS

[ZainabAdeel]

I'm developing an LTI tool for Canvas LMS and I'm curious about observer access. I've configured my tool with the URL, client ID, and secret, and set privacy to public for testing. However, I noticed observers can also access my LTI link.

My question is: Is there a way to restrict observers from launching LTI tools within Canvas courses? Ideally, I'd like my tool (and potentially other tools like Nearpod or Teachermade) to be accessible only to instructors and students, not observers.

Any insights or workarounds on this would be greatly appreciated!
